Application filed September 2, 1922. Serial No. 585,923.

To all whom it may concern:

Be it known that I, ALBERT W. MITCHELL, citizen of the United States,and resident of New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inDispensing Apparatus, of which the following is a specification.

This invention relates to dispensing apparatus and is applicable moreparticularly to holy water or blessing fonts used for devotionalpurposes. I Y

According to the invention, an efficient apparatus can be produced whichwill meet 'allthe requirements of sanitation, noiseless operation andexpeditious self-service when the apparatus is intended to be operatedin turn .by each member ofa congregation of persons-desirous ofobtaining'a drop of holy water necessary for the performance of adevotions j Previously to this" invention dispensing apparatus have beenproposed having means whereby, upon operation of'the same, a determinedquantity of air'is admitted into a hermetically closed'reservoircontaining a liquid and the air admitted permits flow, by gravity alone,of a corresponding quantity of liquid. The action .of such means,however, is not positive and therein differs from the improved meanswhich are designed to act positively and eject a determinable uniformquantity of water at each operation, regardless of the force or speedexercised by the operator when the operation 1 is effected. 1 v

The means for discharging positively or ejecting a measured quantity ofliquid is the chief differentiating characteristic of the improvedapparatus and this means will be particularly described hereinafter andset forth in the appended claims, together with other novel featuresconstituting part of this invention. I

The accompanying drawings illustrate an embodiment of the invention andin these drawings- Figure 1 is a perspective view showing a design ofeasing which is appropriatefor useas a blessing font, V

I Figure 2 is .an elevation partly in section showing theinterior ofthecasing and the mechanism contained therein, and

' Figure 3 is a sectional view .showing a part of themechanismr Theillustrated apparatus constructed and arranged accordingtothis'invention com: prises the casing having the lower section 1 andremovable-top 2. The section 1 is provided with the door 3 through whichaccess is gained tothe interior of the casing.

The means foroperating the mechanism externally consists of the button4v located within a cupped plate 5 fadjacent'to the protrudingspout 6through which the water is'ejected. 7 It will be noted that as both thespout and operating, button are within the cupped plate 5 or flush withthelevel. of the edge thereof said members cannot catch in the clothingof-persons and further the relative position of the spout and button issuch that no matter which finger'the' op erator uses or in .whateverposition the finger may be,,the ejected water will always be depositedon the. finger in contact with the button. Probably after repeated useof the apparatus, there may. be more or less drip, and itisarrangedthat'all drip will pass through slot? in the plate 5 and fallinto drippan 8 located within the casing.

The tank 9 v supported oncross'm'embers .10 within the casing, containsthe water to dispensed; This tank is covered by a loose fitting cover11, so that air may readily enter therein to permit natural flow of thewater throughpipe connection 12 and which flow can ,be shut off orregulated ifdesired, by manipulation of cock-13.

The operating mechanism is simple, bein composed of very few parts ofwhich 14 is a rod capable of beinggiven reciprocating motionby pressingin the button 4 secured at the free end of the rod. "Said buttonis cutaway at 15 so that the button may pass the spout 6. Therod 14: slidesinbearings provided by the standards lfi and 16 and this rod movesinwardly against the resistance offered by coil spring 17 A plungermember is correlated with said rod l i and this plunger member includesthe short length of rod 18 which slides in a bearing provided by the.standardllfi. A shaft 19 having'a threadedend is secured to the rod 18so as to vform a part of the plunger memher. A pistonQO- is carried onthe free end of-said shaft and this piston slides within the cylindricalhead 21 forming-part of the standard 16. A lever 22having forked withinthe split ends of the rods 14; and 18, and by such means the rod 14: andthe'plunger member are connected so as to be coactive.

When the button land rod 14 are in the normal or inner position, thepiston 20, which serves as a slide valve element effectually closes theport leading to the spout 6, and the sleeve 27 sliding. in the cylinder21, bushing 28 and stufling boX 29, prevents leakage of'water at theother end of the plunger member. It will be noted the piston is capableof'being given a certain independent movement relatively to the sliding'1 sleeve 27. This independent movement is regulated by means of theadjusting nut 30 and set nut 31, and by means of this regulation'adetermined measured quantity of water is drawn by suction from'thesupply pipeduring the forward movement of the plunger, and is ejected orforcibly discharged through the spout or outlet during the recedingmovement of the plunger, as will be hereinafter explained in connectionwith the operation of the improved apparatus. v

The standards 16l6' which support the mechanism are mounted on the bedplate 32 which latter member is secured to the block 33 located withinthe casing. f The apparatus is capableof being so adjusted by'means ofthe nut 30 so that a determined quantity of water is delivered at eachoperation. 'In the positionshown in Fig. 2 (by dotted lines) theadjustment is such that there is a space between the end of the sleeve28 and the-nut 30 and which space may be increased or diminished byadjustment of the nut 30. The plunger is permitted to have anindependent movement relatively to the sleeve until the nut 30 meets thesleeve and then the sleeve travels with the plunger causing the closureof the port leading from the supply pipe 12.

The apparatus is operated by pushing the button 4 inwardly thefullextentpermitted and theinward movement of the rodltis transmittedthrough the rocking lever 22, to the rod or plunger member 18. Thepistonfirst moves independently of, the sleeve 27, as above stated, and thismovement creates suction to draw the determined quantityof water throughthe supply'pipe 12. The nut then meets and pushes the sliding sleeveforward to close the supply port,

and when pressure is no longer imparted to the button 4, the coil spring17 will cause the return of all operating parts of tln. mechanism backto their normal position, and the piston in its receding movement willforce the water collected between the'end 01 the sleeve and the pistondown through tht spout 6. It will be understood when the piston andsleeve are in the normal position the piston closes the port leading tothe spout and the ends of the sleeve and piston abut so asto close thesupply port and in this position the apparatus is ready for the nextoperation. 7

' It will be gathered from the above description of the means and theoperation thereof, that {the action of the means is positive, viz auniform quantity of water is ejected at each complete operation of themeans without the aid of air pressure and gravity which are forcesentirely relied upon to efiect op eration of dispensing apparatuspreviously proposed.- And in fact, with the improved apparatus havingthe tight packing of the plunger member, no air 1 whatever is admittedinto the cylinder 21, consequently a perfect pumping action is obtainedto eject a uniform quantity at each operation of the apparatus. 1

- Various modificationsin the construction, arrangement and operation ofthe improved apparatus or means, may be made without departing from thespirit of my invention and it is to be understood any such modificationis covered by the claims appended hereunto.
